my couchbase read 110 connection opened in the server is this normal or not ??
and this is has a connection with CPU Utilization ???
I don’t fully understand your question, but there are a number of ‘internal’ connections between processes in Couchbase. These are used for replication, building and logging the UI statistics, etc. 110 connections sounds a bit high, but you don’t mention what process this is, etc.
It may be normal depending on the number of nodes and configuration. And yes, Couchbase does use CPU when moving data over the connections between processes/nodes.
